CAGE STRUCTURE.

Application filed May 6, 1924. Serial No. 711,321.

To all 'whom t may concern Be it known that i, BERNARD Manno-w, a citizen oi the United States, residing at the city of New York, borough of Mair' hattan, in the county oi' New York and State of New York, have invented certain new and useful improvements in Cage tructures, of which the following is a specification.

1t is Well known that cages, such as the bird cages to which this invention is preterably applied, are usually made of a seriesof parallel rods or bars, generally arranged in upright position. Said bars, being usually long, must, theretore, be provided with means wherewith to brace said bars intermediate of the ends thereotto prevent the occupant of the cage from iorcing its way out between a pair of bars.

The means usually employed for bracing purposes comprisesa cross-piece disposed generally at right angles to said bars and secured thereto against displacement longitudinally of said bars. The various types of means for securing the bars and brace together include holes in the brace through Which a bar may be passed, a crimp in the bar or brace, or an independent member tying the parts together.

This invention contemplates the elimination of the necessity for separate handling of individual bars, or for distorting the vbars or braces, or for making holes in the brace, and involves the clamping of the bars, which are preferably of circular cross-sectional shape, between an outer and an inner sheet. The invention Will best be understood from the description which follows and from the drawings in which,

Fig. 1 is a rear perspective view or' my improved structure,

Fig. 2 is a front elevation of the saine,

Fig. 3 is a top plan View of Fig. 1,

Fig. 4 is a vertical section on the line etw-11 of Fig. 3, h,

Fig. 5 is a horizontal section on the line 55 of Fig. 3, and

Fig. 6 is an elevation of the blank from which the outer sheet of my improved structure is formed.

In the practical embodiment of my invention, 1 provide an outer flat bracing sheet 10 in which oppositely disposed preferably rectangular slots 11 are made to form a series of oppositely disposed tongues 12. In carrying out my invention, the

tongues 12 are iirst bent up substantially at right angles to the remaining outer porl tion 13 as is indicated in Figs. 3, i and 5, after which the bars 14 are passed through the slots 11 into the resulting channel and preferably into contact with the inner surface of the outer portion 13. A flat inner sheet 15 preferably of slightly less width and thickness than that of said-outer porjtion 13 is then placed upon the rods 14,

and into the channel formed by the upright tongues 12.

The final step in assembling my improved structure is to turn over the tongues 12 into firm engagement with the inner sheet 15, whereby the parts are held firmly together against relative displacement, and the inner sheet 15 is hidden from View from the outside of the structure.

It will be understood that my improved structure is Well adapted for the rapid assembling and bracing ot a series of bars at a time, as by means of suitable tools or automatic machinery. l do not Wish to be understood as limiting this invention to the exact details or to shape or proportions of the parts as herein illustrated and described, as it will be clear that changes therein may be made Without departing from the spirit ci the invention.

l claim:

1. In a cage structure, a series of straight substantially cylindrical parallel bars, and means for securing said bars in spaced relation including an outer strip comprising a substantially fiat outer portion and substantially rectangular tongues integral with and bent parallel to said outer portion, said bars being disposed between said tongues so that an element of each of said bars is in contact with the inner surface of said outer portion, and a fiat inner' strip of less Width than said outer strip maintained by said tongues in contact with each of said bars along an element of said bars substantially diametrically opposite said first mentioned element.

2. In a cage structure, an outer strip comprising a flat outer portion, spaced flat tongues integral with and bent parallel to said outer portion, a series of bars of substant-ially circular cross-section disposed in the spaces between said tongues and in contact with the inner flat face oisaid outer portion, and a flat inner strip contacting only with substantially a single element of Y said outer tangular slots in lsaid -vdoubled-over edges VV 10 each of seidgbars disposed between said tongue/sier@ Sad, belts; held. ih placeby the pressure of said tongues, and friotionully holding seidbars in place.

3. In a' cage structure, 'a ontinuous outer strip having :i Hat outer portion, edges` spaced relation yto thereon doubled over in portion and having spacedjvre- Wherebyvv etseriesof tongues vare formed in tance equalto the diameter oppositely disposed pairs of said slots, and a 'Halt continuous inner. strip parallel throughout to the outer portion ot' said outer` istrip, spaced from said Vouter strip u disof said bars, rictionelly maintained in place by said tonguesr` and transmitting the pressure ot' said tongues substantially to a single ele- 1nent of each of said bars.
